To aZZ whom it may concern.-

Be it known that I, JOHN KEENAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Linotype-Machines, of which the following is a specification.

This invention relates to linotype-machines in which the slug or linotype is driven out of the mold and between trimming-knives by a reciprocating ejector, as in the well-known Mergenthaler machines.

One of the objects of my invention is to provide a sectional ejector of simple construction which can be readily varied in width to suit slugs of different lengths.

Another object is to so construct the ejector and cooperating parts that the same can be readily applied to existing machines without reconstructing the ejector-frame or providing special supports or attachments for the improvement.

In the accompanying drawings, Figure 1 is a fragmentary transverse section of the moldwheel, knife-block, and cooperating parts of a linotype-machine of the Mergenthaler type embodying my invention. Fig. 2 is a hori- Zontal section thereof in line 2 2, Fig. 1.

Similar letters of reference indicate corresponding parts in both figures.

A indicates the mold-wheel, disk, or carrier having the usual slot a, which receives the mold B, and C is the knife-block, arranged in front of the mold and carrying the slug-trimming knives 0 0.

D is the main slide or guide in which the usual ejector-slide of the ordinary Mergenthaler machine is guided.

My invention consists in employing in lieu of the customary integral ejector-blade a sectional ejector composed of a number of longitudinal blades or sections E E E E E which are individually movable lengthwise of the guide, so that one or more of the sections can be projected to an operative position and the remaining ones retracted to an inoperative position to adapt the width of the effective portion of the ejector to the length of the reloosely one upon another like the sections, so that they are free to slide longitudinally with reference to each other. These slides are guided in the side face of the main slide D.

One of the slides F, preferably the lowermost, is permanently connected with the usual pitman G or other suitable actuating means, While the remaining slides are normally idle or disconnected from said actuating means and provided with coupling devices of any suitable construction by which one or more of them may be caused to reciprocate with said lowermost or primary slide. In the preferred construction shown in the drawings each slide except the uppermost is provided with a sliding bolt It for coupling it to the slide next above it. This bolt is guided in a transverse groove h of the slide and is adapted tointerlock with the corresponding groove of the contiguous slide, as shown in connection with the two lowermost slides in Fig. 1. The uppermost slide simply has such a groove for receiving the coupling-bolt of the adjoining slide. These bolts are shorter than their guide-grooves, as shown, to permit the bolt of one slide to enter the groove of the slide next above it without shifting the bolt of the last-named slide out of its retracted position. Each of thesebolts is shifted by a hand-lever 2', pivoted to the outer side of the companion slide at z" and engaging in a transverse groove formed in the outer side of the bolt, so that by swinging the lever up or down the bolt is shifted into or out of engagement with the next slide. The downward stroke of each lever is preferably limited-by a stop or pin is, projecting from the side of the corresponding slide and arranged to arrest the lever before the companion bolt reaches the lower end of its guide-groove, thereby leaving the lower end of said groove vacant for the entrance of the bolt of the slide next below. The shifting-levers have laterally-projecting thumb-pieces 2' which are preferably countersunk in transverse grooves or recesses Z, formed in the adjacent faces of the slides to render the construction of the parts more compact.

In the use of the improvement as many slides are coupled to the primary or active slides E as is necessary to render the aggregate width of the connected ejector-sections equal to the length of the slugs used in the machine for the time being, such coupled sections being reciprocated together practically as a single ejector-blade, while the other disidle sections are carried by said arrested section they will also be prevented from advancing beyond the rear side of the mold.

For the purpose of alining the upper sections E E E E* in their rearmost position and also for preventing rearward displacement of the same a stop on is provided. This stop is preferably arranged on the main slide in position to be engaged by the rear ends of the upper sections, as shown in Fig. 1.

The coupling-bolts are held in position by the frictional contact of their shifting-levers with the slides F;

The ejector-sections may be of any suitable Width, the width of those shown in the drawings being about equal to the length of a halfcolumn slug, thus requiring two sections to be coupled together to adapt the ejector to a column-slug. The ejector may, however, be divided into narrower sections, if desired.

The mold illustrated in the drawings is designed to cast single-column slugs; but the slot (0 of the mold-wheel is of sufiicient length to receive the longest molds required, as is common in such machines.

By my improved construction the operator can readily narrow or widen the sectional ejector to suit different-sized slugs without the inconvenience and loss of time incident to interchanging the integral different-sized ejecting-blades heretofore employed, it being only necessary to couple together a greater or less number of the ejector-sections, according to the length of the required slugs.

I claim as my inventi0n-- 1. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of-the guide, and coupling devices carried by the sections and each arranged to engage an adjoining section, whereby two or more of the sections may be connected together for increasing the effective width of the ejector, substantially as set forth.

2. In a linotype-machine, the combination with the moldand a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of the guide, a plurality of slides arranged in said guide and each carrying one of the ejector sections, means for reciprocating one of said slides, and means for coupling the slides to one another to vary the width of the ejector, substantially as set forth.

3. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of the guide, means for actuating the lowermost section, and means carried by the sections for coupling each section to the one next above it, substantially as set forth.

4'. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of the guide, coupling devices carried by the sections and each arranged to engage an adjoining section. and actuating means for the coupling devices also carried by the ejector-sections, substantially as set forth.

5. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composedof sections individually movable lengthwise of the guide, coupling-bolts carried by the sections and arranged to engage adjoining sections, said bolts being movable transversely of the sections,and means for reciprocating one of the sections, substantially as set forth.

6. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of the guide, slides arranged in said guide and carrying the respective ejector-sections, sliding couplingbolts guided transversely on said slides, and shifting-levers pivoted to the slides and engaging said bolts, substantially as set forth.

7. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of the guide, slides arranged in said guide and carrying the respective ejector-sections, each slide having a transverse guide-groove adapted to register with the corresponding groove of the adjoin,

ing slide, and sliding bolts guided in said grooves, substantially as set forth.

8. In a linotype-machine, the combination with the mold and a guide arranged adjacent thereto, of a slug-ejector composed of sections individually movable lengthwise of the guide, slides arranged in said guide and carrying the respective ejector sections, coupling bolts guided transversely on the slides, and shiftinglevers for said bolts pivoted to the slides and having lateral thumb pieces which extend into recesses of the slides, substantially as set forth.
